چکیده: (19923 مشاهده)
Wheel/rail contact simulation is one of the most complicated problems in the modeling of railway vehicles.
The wheel/rail interaction plays a unique role in rail vehicle dynamics. In this paper, the dynamic response
of the wheel on irregular rail track is analyzed with analytical approach using the method of Multiple
Scales (MMS). The Hertzian contact theory is used to obtain the relationship between normal contact force
and the displacement of the mass center of the wheel. Analytical approach is expanded for performance of
train’s wheel travelling on the rail. To validate the method presented in this paper, responses of the model
using MMS method are compared with the results obtained from the Runge–Kutta numerical solution.
Finally effects of the wheelset preload on response frequency have been studied.
